Hershey Kisses, a pumpkin, and MaKey MaKey create an open source Halloween

We've been anxiously awaiting our chance to mess with a MaKey MaKey after we wrote this post, and we finally got our hands on one just in time for Halloween. MaKey MaKey's are based off Arduino, and you plug them into your computer with a USB cord. Basically you can alligator clip anything that conducts electricity and to make anything into a key.

After painstakingly carving our Opensource.com pumpkin, we used that, along with five pumpkin Hershey Kisses as our keys. We found a piano keyboard on the MaKey MaKey website that was written in Scratch, so you can easily change the keyboard to create your own version.
